About the Author Michael Miller is the author of more than three dozen best-selling technology-oriented reference books. You can contact him directly at [email protected]. Introduction Everyone is always looking for the “next big thing”—especially in the world of technology. Emerging technologies attract interest because of their future application (how will it affect my life?), because of their potential investment value (it’s good to get in on the ground floor of something big), and, quite frankly, because they’re kind of cool. Bluetooth is just such an emerging technology. Many—including me—think that it’s going to be the “next big thing” in the computing and telecommunications worlds. If you follow the technology news, you’ve probably heard about Bluetooth already. It’s a new wireless technology that promises not just to eliminate the cables that connect our computing and electronics equipment, but also to spawn new and exciting applications for electronic information exchange, electronic payments, and who knows what else. And, if it does half of what some people predict, it’s going to be big. It’s that future potential that inspired me to write this book. The technology is interesting, yes, but Bluetooth also has the potential to dramatically affect the way we do many things in our everyday lives. It’s quite possible, once the technology hits a critical mass, that we’ll find Bluetooth driving literally dozens of our different activities each day. When we use our computers or PDAs, we’ll be using Bluetooth technology. When we use our desktop or mobile phones, we’ll be using Bluetooth. When we drive our cars, Bluetooth will be along for the ride. When we go shopping, or traveling, or out for a night on the town, Bluetooth will be there. If you’re at all like me (and millions of other technology enthusiasts), you want to be in on the Bluetooth revolution from the very beginning. Maybe you’re the guy who has to be the first on his block with all the new toys and gadgets. Maybe you see how Bluetooth can provide a better way to do those tasks that are slow and cumbersome today. Maybe you see an investment opportunity, and want to know which companies will benefit from a Bluetooth boom. Maybe you work for a company that is considering adding Bluetooth functionality to its products. Maybe you just want to find out what all the fuss is about. Whichever of these statements best describes your interest in Bluetooth, you’ve come to the right place. Discovering Bluetooth is the first book to examine Bluetooth from a consumer, rather than a technical, perspective. This book will tell you what Bluetooth is about, how it works (in general terms—not a lot of technobabble here), and how it’s likely to impact your daily life. You’ll learn the history of Bluetooth (it came from Sweden...), view some of the first Bluetooth products to hit the market, and discover all sorts of interesting potential applications of the technology. In short, whatever your interest in Bluetooth, you’ll find the information you seek within these pages. To make it easier to find precisely what you’re interested in, Discovering Bluetooth is divided into three major sections, as follows: • Part I, Discovering Bluetooth, contains three chapters that provide the essential background and history of the Bluetooth technology and of the consortium of companies that are developing Bluetooth for consumer consumption. • Part II, What Bluetooth Does, contains two chapters that describe a number of practical applications of the Bluetooth technology, as well as present a multitude of first-generation Bluetooth-enabled products that are either currently available or will be available soon. • Part III, How Bluetooth Works, contains six chapters that present the technical background behind the technology, discuss potential competitors to Bluetooth and barriers to its success, and predict how Bluetooth will develop in the future. If you get stumped anywhere in the text, you can turn to the useful reference information contained in this book’s appendixes and glossary. Here you can find a list of Bluetooth-related acronyms (and this technology is very acronym heavy!), a glossary of Bluetooth-related terms, the basic technical specifications behind the technology, and a helpful list of other Bluetooth resources that you might want to check out. I think Bluetooth is going to be a big thing; that’s why I wrote this book. I hope that Discovering Bluetooth provides the information you need to make up your own mind about Bluetooth—and to whet your appetite for this exciting new technology! Part I: Discovering Bluetooth In This Part Chapter 1: Introducing Bluetooth Chapter 2: How Bluetooth Came to Be Chapter 3: The Bluetooth Industry Chapter 1: Introducing Bluetooth There’s a Bluetooth in your future. No, this isn’t the kind of blue tooth that requires expensive dental whitening. This Bluetooth is a technology that promises to eliminate most of the cables that connect your various personal computing devices—and to create new types of smart wireless communications. This book is your guide to Bluetooth, a consumer-level overview of the technology and its possible applications. Throughout the rest of this book you’ll learn all sorts of details about Bluetooth—what it is, what it does, how it does it, and how you’ll use it. Before we get to those details, however, this chapter provides you with a general overview of the Bluetooth technology. So even if you’ve never heard of Bluetooth before, you’ll find out what all the fuss is about—and discover how and why you’ll soon be using Bluetooth technology in your daily life. Visions of a Wireless World The computing, communications, and consumer electronics industries have introduced many benefits to today’s consumers. Of course, they’ve also introduced many headaches, not the least of which is the necessity of connecting all these devices to each other, usually with a phalanx of cables and wires that are both annoyingly messy and mind-numbingly confusing. Wouldn’t it be great if you could connect your printer to your PC—or your PC to your PDA or your PDA to your phone line—without fumbling with the necessary cabling and worrying about whether you’re using the right type of connector? If you’d like to nix all that messy cabling, Bluetooth is for you. Bluetooth technology enables wireless connections between any number of computing, communications, and consumer electronics devices—and promises much more than that, including “smart” device recognition and synchronization. At its most basic, Bluetooth technology will usher in a world of wireless connections. Using short-range radio wave transmissions, Bluetooth technology will enable all your different electronic devices to connect to each other—without wires. Cableless Computing Consider the common chore of hooking up a printer to your personal computer. Today you have to buy a big, thick, ungainly cable with multi-pin connectors on either end, plug the cable into the proper ports on the back of both your PC and your printer, and go through a complex setup procedure to make sure your PC recognizes the printer.

  • 1394 Standards and Specifications Summary Michael D
    1394 Standards and Specifications Summary Michael D. Johas Teener Chief Technical Officer Zayante, Inc. 269 Mt. Herman Rd. #201 Scotts Valley, CA 95066-4000 [email protected] Introduction With the quickening introduction of products based on IEEE 1394 (Firewire or iLink depending on your religious preferences) has come a proliferation of specifications, standards, architectures, and guidelines for these products. This article is intended to be a guidebook to those various documents, with an emphasis on how they should be applied to design and build products. There are two parts to this paper: a summary of the standards and some idea of their relationship with each other, and a detailed listing of the standards themselves along with appropriate references. This detailed listing is maintained by Burke Henehan, the 1394 HW Engineering Lead at Texas Instruments ([email protected]), with help from the author of this paper. Any corrections to this paper are gratefully solicited, and should be sent to both the author and Mr. Henehan. Why so many 1394 specifications? At last count, there were over 70 documents that attempt to define the characteristics of 1394-based devices. This is not necessarily an indication of complexity, it is instead an indication of the vast number of applications of 1394. There are, in fact, only a few specifications that all designers must be aware of: the original IEEE 1394-1995 document and its “a”, “b”, and “dot one” extensions as well as IEEE 1212-1991 (ISO 13213) and its revision. The other 60-odd specifications cover the various applications of 1394, particularly in the consumer electronics and PC product spaces.
